Give it a go kimlck because it would be a shame to let it go past it`s `use by` date.
I find the WAGG doesn`t need feeding in large amounts anyway, so a small teaspoonful is fine and can last more than a few days depending on how greedy the hamster is!
I`ve stopped worryring about diabetes and commercial mixes althogether now because I feel it`s worrying over nothing. If a hamster is going to develope diabetes, it probably will regardless of it`s daily rations. Commercial mixes are just that. Nutritionally made to have everything a hamster requires and if some of the dried ingredients happen to be a little sweetened, it`s actually beneficial to have some sugar in the diet anyway rather than none at all. x
